Albertsons LLC plans to shutter nine Colorado stores in the second wave of closures since last summer.

The company notified workers and union officials of the move today and said the closures would be completed by March 20.

The targeted stores include three in Westminster, two in Colorado Springs and one each in Denver, Greeley, Lakewood and Parker, said Dave Minshall, a spokesman for United Food and Commercial Workers Local No. 7.

Four of the nine stores targeted for closure are represented by the local union. In a letter to union president Ernie Duran, the company said 234 people worked at the unionized stores.

Union workers will have the option of moving to open positions at other stores or “bumping” lower-seniority workers at other stores. Those who cannot transfer or are not at unionized stores will be laid off.

Today’s closures mark the second round of cuts by Albertsons LLC, which purchased Albertsons stores in Arizona, California, Colorado, Florida, Louisiana, Nebraska, New Mexico, Oklahoma, South Dakota, Texas and Wyoming last year.

The company shuttered 16 stores in the state late last summer. Following the new closures, there will be 32 Albertsons stores remaining in the state.
